LIGHTIITG-FIXTURE.

Specification of Letters Patent. Patented M31223, 1920- Application filed. February 28, 1919. serial ire. 279,884.

To all whom it may concern):

Be it known that I, MYER M. MARKs, a citizen of the United States, residing at Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Lighting Fixtures, of

which the following is a specification.

ll ly invention relatesto lighting fixtures such as are described in Patent No. 12300 16, which fixture employs a reflector and a diffusing globe to shield the eyes from the direct rays emitted by the filament of the electric lamp and has for its object to construct an improved holder or support for holding the reflector and globe in position.

The invention is more specifically designed as an improvement upon the construction shown in my co-pending applications Serial Numbers 279,885 and 279,886, filed February 28, 1919. In the devices therein shown. the parts which contact with the globe and reflector are formed from the metal strips which engage the reflector and globe respectively.

My present improvement provides a simple and less expensive means to engage the lips on the reflector and globe respectively.

My means of accomplishing the foregoing object may be more fully understood by reference to the accompanying drawings which are hereunto annexed and which form a part of this specification in which Figure 1 is a vertical sectional view of a lighting fixture of the character referred to equipped with my improved holder.

Fig. 2 is an enlarged sectional view of my improvement.

Fig. 3 is a detail bottom plan view of my improved holder. v

Fig. 4 is amodified form of construction.

Similar reference numerals refer to simi lar parts throughout the entire description.

As shown in the drawings: the device is applied to a lighting fixture comprising a holder or shell. 10, which may be suspended in any of the usual. or customary ways for accomplishing this result. A socket 11, is secured inside of the shell 10 and has an electric light bulb 12, mounted therein. This bulb is surrounded by a globe 13, the upper part of which terminates in a neck 141 the neck being provided with a lip 15.

A reflector 16 surrounds the globe 18. for the purpose ofredirecting the rays of light downwardly. The reflector has a neck 17 whichis also provided with a lip 18.

My improved holder comprises a tripod, mounted inside of the shell 10, and provided with three downwardly depending legs 19. Mounted in these legs in a plane adjacent the lips of the globe and reflector respectively are pins 20 and 21, the inner. ends of which are so shaped as to conform to the lips 15 and 18 of the globe and reflector respectively when they engage them. The pins may be threaded into the legs 19 welded or secured in any convenient or desired. manner. Annular bands and 23 are secured to the legs 19, adjacent the pins 20 and 21, these bands are arranged to be detachably secured in a contracted position as shown. The securing means comprise a metal plate, provided with slots 24 and 25 on the edges of which are formed a plurality of teeth 26 and 27.

It will be apparent from the foregoing description that a considerable amount of metal is saved over the construction shown in my co-pending applications and that the die work required will be very much less.

In Fig. 4 I have shown a modified form of construction in which the engaging portion 30, of the legs 19 is formed by punching out a tongue from the metal strip forming the legs 19, of the tripod.

It will be apparent that this construction is also a great metal saver over the former constructions and it may be found in practice to be even better than the pins hereinbefore described.

Although I have described specific details of construction I do not desire to be limited thereto, except that such limitations may appear in the hereinafter contained claims.

Having described my invention what I regard as new and desire to secure by Letters Patent is:

1. A holder for a globe, a. reflector having lips formed-thereon comprising a tripod, two pins projecting from the legs of the tripod in planes adapted to engage the lips on the globe and reflector respectively and means securedv to the legs of the tripod to detaohably hold said pins in contact with the lips on the globe and reflector.

2. A holder for a globe and reflector each of which is provided with a. neck terminating in. a lip. a plurality of metal stripe, a plurality of pins projecting inwardly from said strips shaped to conform to the lips on the globe and reflector respectively and bands secured to said strips to detachably hold said members in contact with the said 5 reflector and globe respectively.

3. A holder for a globe and reflector each of which has a neck provided With a. lip, a plurality of metal strips, tongues punched therefrom, in spaced relationship to engage the lips of the reflector and globe respectively, bands secured to the said strips to cause said engagement and means to detach- .abl maintain said en 'a ement when it has taken place.
